This series takes place at
Darwin Mine, adjacent to
Death Valley National Park in California and has six episodes, all involving
space exploration. Four scientists from the previous series (Ellen McCallie, Jonathan Hare, Mike Bullivant, and Kathy Sykes) are featured plus a new scientist,
Iain Stewart, the show's first
geologist. Mike Leahy from the previous series is not featured in this series. • "'Rover": Build a
rover, find water and
purify it. • "Communication": Send a communication in a way that didn't rely purely on
sound (by altering the vibrations of reflected
sunlight, which is then detected by a transistor functioning as a light detector), and make a
pen that works in
zero gravity. • "Spacesuit": Design a
cooling system for a spacesuit. • "Impact": Measure the size of the meteor that created
Barringer Meteor Crater. Iain and Kathy travel to Arizona to see the crater. Mike stays behind, and experiments with impact. Jonathan and Ellen make a
telescope using an eyepiece and mirror they find in the chest given to them at the start of the episode (their task was to actually measure the size of a crater on the
Moon). • "Aerial Surveyor": Build a device with a
camera that could survey a large area from the air. Find the center of one of the largest earthquakes to hit America that took place back in 1872 in California, and estimate what it measured on the
Richter scale. Mike creates a system that filters carbon dioxide, just as the
astronauts of
Apollo 13 were forced to do when an explosion ruptured an oxygen tank. • "Rocket": Design
rockets that can launch an
egg into the air and return it safely to earth. Three different rockets are attempted by three of the scientists, while the remaining two work on a
parachute system. ==Series 5==
